    The kext ordering for IC2 is not correct.  Move VoodooI2C down between voodooIput and VoodooI2CHID, that should fix it.
    As for booting order, try setting the order in the BIOS boot Option. Move Windows Boot Manager to the top, above OPENCORE.

    At the OC picker, select the OS you want as default to load, hold Ctrl + enter. Next time your reboot, it'll automatically boot to that OS until your reset NVRam of course.

    Your order is wrong as I noted, order is important!
    You'll need the plugins 1st:
    voodooInput voodooGPIO voodooi2cServices voodooI2c voodooI2cHID Add voodoo elan if it's not working
    Get rid of IntelSnowMausi // for legacy devices

  19. Jake Lo's post in Latitude E7450 OC Big Sur Post-Install was marked as the answer   
    After scratching my head for awhile, I gave in and try booting your files. Just as you noted, webcam and audio both are not working. After comparing line for line and making different changes on the Config.plist and rebooting, there was no changes to the webcam and audio. I know it has something to do with IRQ so I look carefully at the HPET patch and notice a difference in the patches you have and mine. After making that one change and reboot, all usb port and audio started working. 
    Here's your new config file, add the SSDT to ACPI. Enjoy!
